The TPA005D02 Audio Power Amplifier Evaluation Module

The TPA005D02 Class D Stereo Audio Power Amplifier Evaluation Module is
powered by a TPA005D02 class D stereo power amplifier integrated circuit
capable of delivering greater than 2 W of continuous power per channel into
4-

Ω

loads. The amplifier IC operates in the bridge-tied load mode for maximum

efficiency. The evaluation module includes onboard switches for muting and
shutdown and a control input pin for muting. A pair of indicator LEDs are
mounted on the module to display power supply undervoltage and amplifier
IC thermal status.

The module can be used with the TI Plug-N-Play Audio Amplifier Evaluation
Platform (Figure 3 –1) or wired directly into circuits or equipment. The module
has single in-line header connector pins mounted to the underside of the
board. These pins allow the module to be plugged into the TI platform, which
automatically makes all the signal input and output, power, and control
connections to the module.

The module connection pins are on 0.1-inch centers to allow easy use with
standard perf board and plug board-based prototyping systems. Or, the EVM
can be wired directly into existing circuits and equipment when used
stand-alone.

The module appears in Figure 3–2 and its schematic is shown in Figure 3 – 3.
